Scientists sometimes categorize galaxies based on their shapes and physical features.

The massive cluster of galaxies named Abell 2744 appears in the foreground of this image. The de Vaucouleurs system for classifying galaxies is a widely used extension to the Hubble sequence, first described by Gérard de Vaucouleurs in 1959. De Vaucouleurs argued that Hubble's two-dimensional classification of spiral galaxies—based on the tightness of the spiral arms and the presence or absence of a bar—did not adequately describe the full range of observed gala…
